Double blowjob.

"Both of you, get on your knees," he ordered both girls. They both complied and looked up at him as he approached them. He undid his pants and let his cock spring loose. "Both of you, blow me," he ordered them.

"Alright!" Darkness beamed, grabbing his member, and guiding it into her mouth immediately.

Megumin however, hesitated. "Uh..." she said apprehensively. Seemed that while he had programmed her to to solo blowjobs on request, she didn't quite consider assisted ones the same thing. Kazuma was just about to snap his fingers and get her to do so, before she leaned forward on her own and began to lick his testicles.

"Good girl," he grinned as he lowered his hand. She simply moaned as she sucked one of his balls into her mouth, fondling the rest of his scrotum with her other hand. "Switch," he commanded them.

Darkness pulled off of his cock and went down as Megumin went up, licking his shaft a couple of times before she engulf his shaft as Darkness had done, and Darkness was licking his scrotum.

Every minute, he told them to switch, moaning in pleasure each time, before he felt his release impending. "I'm going to cum girls," he moaned, before snapping his fingers, trancing Megumin, and saying, "I'm going to cum on your face."

Untrancing, Megumin nodded, pulling back alongside Darkness, and sticking out her tongue, as Darkness did the same. Kazuma grunted, before his seed spurted onto their faces. Megumin blinked as one hit her tongue. When he finished, she licked a bit, befuddled, but not unpleasantly so. "...your cum tastes different," she finally said, getting a chuckle from Kazuma.
